Xanthomonas oryzae (Xo) is one of the important pathogenic bacterial groups affecting rice production. Its pathovars Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas oryzae pv. oryzicola (Xoc) cause bacterial blight and bacterial leaf streak in rice, respectively. Xo infects host plants by relying mainly on its transcription activator-like effectors (TALEs) that bind to host DNA targets, named effector binding elements (EBEs), and induce the expression of downstream major susceptibility genes. Blocking TALE binding to EBE could increase rice resistance to the corresponding Xo.

We used CRISPR/Cas9 to edit the EBEs of three major susceptibility genes (OsSWEET11, OsSWEET14 and OsSULTR3;6) in the rice varieties Guihong 1 and Zhonghua 11. Both varieties have a natural one-base mutation in the EBE of another major susceptibility gene (OsSWEET13) which is not induced by the corresponding TALE. Two rice lines GT0105 (from Guihong 1) and ZT0918 (from Zhonghua 11) with target mutations and transgene-free were obtained and showed significantly enhanced resistance to the tested strains of Xoo and Xoc. Furthermore, under simulated field conditions, the morphology and other agronomic traits of GT0105 and ZT0918 were basically the same as those of the wild types.

In this study, we first reported that the engineering rice lines obtained by editing the promoters of susceptibility genes are resistant to Xoo and Xoc, and their original agronomic traits are not affected.

We measured root dynamics of both overstory deciduous oak (Quercus crispula) and understory evergreen dwarf bamboo (Sasa nipponica), the two major species in the forest. Snow removal advanced the timing of peak root production by a month both in total and in Sasa, but not in oak. There was a significant interaction between snow removal and plant form on root production; this indicates that enhanced Sasa root production following snow removal might increase its ability to compete with oak. In contrast, snow removal did not enhance root mortality, suggesting that the roots of these species tolerate soil freezing. The earlier snow disappearance in the snow removal plot expanded the growing season in Sasa. We speculate that this change in the understory environment would advance the timing of root production by Sasa by extending the photosynthetic period in spring. We propose that different responses of root production to reduced snow cover between the two species would change the competitive interactions of overstory and understory vegetation, influencing net primary production and biogeochemistry (e.g., carbon and nitrogen cycles) in the forest ecosystem.Decellularized scaffolds have been found to be excellent platforms for tissue engineering applications. The attempts are still being made to optimize a decellularization protocol with successful removal of the cells with minimal damages to extracellular matrix components. We examined twelve decellularization procedures using different concentrations of Sodium dodecyl sulfate and Triton X-100 (alone or in combination), and incubation time points of 15 or 30 min. Then, the potential of the decellularized scaffold as a three-dimensional substrate for colony formation capacity of mouse spermatogonial stem cells was determined. The morphological, degradation, biocompatibility, and swelling properties of the samples were fully characterized. The 0.5%/30 SDS/Triton showed optimal decellularization with minimal negative effects on ECM (P ≤ 0.05). The swelling ratios increased with the increase of SDS and Triton concentration and incubation time. Only 0.5%/15 and 30 SDS showed a significant decrease in the SSCs viability compared with other groups (P  less then  0.05). The SSCs colony formation was clearly observed under SEM and H&E stained slides. The cells infiltrated into the subcutaneously implanted scaffold at days 7 and 30 post-implantation with no sign of graft rejection. Our data suggest the %0.5/30 SDS/Triton as an excellent platform for tissue engineering and reproductive biology applications.
Flexible fibreoptic laryngoscopy (FFL) is a technique of laryngeal visualization. The instrument (flexible laryngoscope) is relatively scarce in resource challenged countries. Where available, it is a useful compliment to the armamentarium of clinical tools at the disposal of the otolaryngologist. We evaluated the diagnostic value of flexible fibreoptic laryngoscope in a tertiary health institution in Nigeria. And we hypothesized that its diagnostic precision is comparable to direct laryngoscopy.

This is a retrospective study of records of 360 patients referred for FFL at the ENT clinic. click here Sensitivity and specificity of FFL for laryngeal lesions were determined using direct laryngoscopy (DL) as the gold standard.

Of the 360 FFL reports studied, 336 additionally underwent DL. FFL findings in 311 (92.6%) cases were comparable with that of DL. FFL had a good detection rate for vocal cord palsy (sensitivity 100%, specificity 80.7%). Pick-up rate for vocal nodules, polyps, papillomatosis and palsy were statistically equal for FFL and DL (p value = 0.96). Diagnostic accuracy of FFL was good for supraglottic (sensitivity 100%, specificity 88.0%) and glottic (sensitivity 100%, specificity 92.3%) tumours; relatively lower for subglottic (sensitivity 83.3%; specificity 100%) and transglottic (sensitivity 80.0%, specificity 100%) tumours; and least for tumours involving more than on subsites (sensitivity 50%, specificity 100%).

The sensitivity and specificity of FFL were not the same for all endo-laryngeal lesions; yet, the overall diagnostic accuracy of FFL is comparable with DL. Clinicians should be mindful of this variability to optimize its application.
